expeople1 [14]

Answer:

The correct answer is C) arachnoid mater.

The arachnoid mater is in the middle of the other two layers and it is very important since it holds the <u>cerebrospinal fluid (CSF)</u> in its interior. Arachnoid mater has finger-like projections that enter the dural venous sinuses and are called <u>arachnoid villi</u>. These villi are responsible for the diffusion of CSF into the blood.

<u />

<u>Why do forensic scientists use it?</u>

In forensics, the is used to accurately determine a body's time of death. The fluids within the vitreous humor take longer to undergo the decay or putrefaction process. Thus, toxicology may accurately determine this based on the rising potassium levels within the vitreous humor- the levels rise in a steady, predictable pattern for certain time intervals. The potassium levels are usually used in the determination of the time of death or post-mortem interval of a corpse
